I was able to complete it by changing world tier to tier 1.
I had read stuff about making sure the event outside isn’t active but that didn’t seem to make a difference. Switched to tier 1 and it was good. Or I guess try a different tier if you’re currently playing on tier 1.
If you go into the cave and the wall at the back is attackable before you talk with the NPCs, then it’s still bugged. The wall should not become attackable until after she gives her speech.
Like I said… No. Balls.
